摘要:
The quark matter symmetry free energy and the thermodynamical properties of strange quark matter (SQM) in strong magnetic fields and non-zero temperature cases are discussed in this work within Nambu-Jona-Lasinio (NJL) model by considering two kinds of vector interactions. The properties of the proto-quark stars (PQSs) are also studied by introducing a density-dependent magnetic field strength distribution and assuming two 'extreme' magnetic orientation cases inside the quark stars (QSs). The results indicate that the strength and orientation d...
